I know where these came from .
They are new old stock surplus Browning 1919 MG barrels originally for the Swedish WW2 MG .
If they can actually get these out of the US & into Canada they would be a good base to convert a M98
Or convert a semi 1919 to 8x63

Police said in an email there was "no active shooter situation" but seven youths who had a slingshot were taken into custody.

These barrels are originally for the water-cooled gun that's why they are lighter than a standard 1919A4 barrel .
You will have to make a press fit bushing for the end of the barrel to the same diameter as the 3006 barrel .
Have that bushing pressed on the end of 8x63 barrel so it will be supported in the barrel bushing in the nose cap .
You will also need to make a split bushing for the breech end to mimic the size of the 1919A4 barrel .
you may also have to modify the bolt slightly as the 8x63 has a slightly thicker rim than the 06
